Coal assay Wikipedia

Relative density. Relative density or specific gravity of the coal depends on the rank of the coal and degree of mineral impurity. Knowledge of the density of each coal play is necessary to determine the properties of composites and blends. The density of the coal seam is necessary for conversion of resources into reserves.

Bituminous coal ispatguru

Sep 17, 2018 · Bituminous coals have true relative density which refers to the coal mass per unit volume, excluding the pores in the coal in the range of 1.25 g/cc to 1.5 g/cc (grams per cubic centimeters). The scratch hardness (Mohs hardness) is the relative hardness determined by scratching the coal surface with 10 types of standard mineral.

Relative coal density is measured as specific gravity. Specific gravity is the ratio of the mass of an object (solid or liquid) to the mass of an equal volume of water at 4°C. For reference, the specific gravity of water is 1. Materials with specific gravities of less than 1 float in water. Specific gravities that are greater than 1 sink in water.
